not all custom mp3 tags are shown?

For example, all files in my library appear when browsing by artist, but when browsing by artistsort, the mp3 albums get excluded. The same goes for my custom tag label.

There's a known issue with the LABEL tag. The ID3v2 specification uses the TPUB 'Publisher' frame to hold Publisher or Label information. Some tagging programs (but not Mp3tag, according to this page) put LABEL tags into TPUB frames, and MinimServer currently doesn't read TPUB frames. I could change MinimServer to read TPUB frames, but the result would be that your Label tags are displayed as Publisher tags.

ARTISTSORT is problematical as well. From a bit of web searching, Mp3tag writes this to the TSOP 'Performer Sort Order' frame. This is only valid in ID3v2.4, but Mp3tag writes it to ID3v2.3 as well. MinimServer currently doesn't read the TSOP tag. I could change this, but the result might be that your ArtistSort tags are displayed as PerformerSortOrder tags, and this might only work if your files are written with ID3v2.4 tags.

When I have a spare day or two, I'll gather information on all the tag mappings used by all the tagging programs, try to guess which of the many alternative mapping choices represent the prevailing industry standard, and implement those mappings in MinimServer.
